yksilöihin

Yksilöihin is a Finnish noun form that translates roughly as “to the individuals” or “into the individuals.” It is the illative plural form of the word yksilö. The base yksilö refers to an individual—a single entity, such as a person or an organism—and is used to denote a single member of a larger set, as opposed to the group as a whole.

The noun yksilö means an individual and is commonly used to refer to a single member of a population or dataset. In scientific, sociological, and everyday language, yksilö can denote a person or organism considered as a discrete unit within a larger collection. The plural nominative is yksilöt, while the illative plural is yksilöihin, used when indicating direction toward or into multiple individuals or when discussing actions or analyses applied to individuals.

Grammar-wise, Finnish nouns change form for case and number. For yksilö the illative plural ending -iin yields yksilöihin. This form is used to express movement toward the individuals or to refer to things directed at or applied to them, depending on the context. For example, in research writing one might encounter phrases that treat data or interventions as directed at yksilöihin.

Usage and context: Yksilöihin appears mainly in formal or academic Finnish, especially in sociology, psychology, epidemiology, and data analysis, where the unit of analysis is an individual rather than a group.
